High Temperature Easily Removed Flux

Described is a high temperature easily removed flux in which flux residue on products which require high reliability is significantly reduced.

A mixture of benzlyl alcohol flux may be dissolved in a mixed isomeric 5-ring polyphenyl ether. Such an ether is now sold under the trade name OS124* oil. The ether has a very high boiling point of approximately 530 Degrees C, is inert and is easily removed with many common solvents.

By submerging the parts to be soldered in the mixture they are kept from air and not able to oxidize. The rosin in the solution is prevented from depositing out on the material being treated, while providing flux o the material being treated. Thus the use of this ether as a carrier prevents the creation of residue at the high temperatures involved in such soldering operations. * Product of Monsanto Company.
